WING FRAME FOR S'iREET SIGNS v Filed Nov. 29, 1940 Patented May 26, 1941 2,242,331 wine FRAME FOR s'rnnn'r sicns 10 Claims.

This invention relates to street or other sign holders and more particularly to a wing frame for street signs.

One object of this invention is to provide a cornerpiece with one or more integral holding 7 arms and a sign holding frame for each holding arm, said sign holding frames being vertically insertable in chambers in each holding arm, and means for wedging said frame in its assembled. position without the use of bolts and nuts.

Another advantage of the present invention resides in the provision of a wing frame for street signs which will not sag due to the weight of the sign nor become horizontally or vertically displaced.

A still further advantage of the present invention is to completely eliminate the use of bolts, nuts or similar retaining means in the entire assembled construction of the holding frame and holding arms.

Yet another purpose of the present invention is to provide a frame of this character which is easy to manufacture and easy to assemble.

A further aim lies inthe provision of a frame of this type which is doubly locked, thus preventing tampering with or the unauthorized removal of the sign.

Still another advantage of this invention is to provide means for securely connecting the holding frame to the holding arms, so as to make it impossible for the frame to become loose due to vibration or wind.

These and other meritorious objects, which will become more fully apparent as this description proceeds, are accomplished by the novel construction and combination of simple parts, hereinafter described and illustrated in the accompanying drawing, forming a material part of this disclosure, and in which:

Figure 1 is an inside elevational View of a street sign constructed according to my invention and showing one sign holding frame in assembled position.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a sectional View taken on line of Figure 1.

Figure 4 is a fragmentary front elevational view of a holding arm and holding frame ready to be vertically dropped into the holding arm and showing a vertical key way, parts being broken away to show the inner construction.

Figure 5 is a plan view of the end of the frame engaged in the extension of the holding arm, showing the key pin between both members.

Figure 6 is an inside perspective view of the cornerpiece, one of the sign holding frames being shown as assembled.

Referring in greater detail to the accompanying drawing, the number Ill designates in general a metal post, either tubular or of any other desired cross-section, which is suitably anchored in the ground. Mounted on post I0 is a cornerpiece H of the same cross-section as the post l0, and it is adapted to partially encircle said post.

The cornerpiece H is formed with two vertical holding arms I2 and 13 arranged in fixed angular relationship toeach other. Both arms are of identical construction and are provided with a vertical slot l4 located in horizontally disposed extension pieces 25. The slot l4 provides means for retaining therein the end of a sign holding frame in a manner to be hereinafter described.

The sign holding frame consists of superimposed frame members l5-l6, normally riveted together. Each of said members has an opening for the display of a sign, and if desired an additional smaller opening for an additional sign. These openings are indicated at H and I8.

The superimposed frame members !5 and I6 are usually riveted together, as at I9, 20, I9, 26', or cast together so as to be permanently united and at the same time leave a space between them for the insertion of a sign plate.

The vertical slot 14 is positioned in the outer end of extension 25. This slot M is so arranged, that its opposing walls 2! or 22 or both are inreaching.

The slots 25 in the upper extensions are through-reaching, while the slots in'the lower extensions are provided with stops 2'6.

Thus, when the frame has been vertically in-' serted into its assembled position in the extensions, it cannot be displaced horizontally due to the inreaching portions 2'l-2'|' and it cannot be displaced vertically due to the stop 25 and wedging key pin 29 which is vertically inserted into key slot 30 in the extension and cooperating key slot 30' in the end of the frame. The walls '2l and 22 may be inreaching in such manner, that a narrower point is reached as indicated at 21 and a wider portion as at 28.

When assembling the street sign frame, it is merely required to drop the ends 3! of the frame into slots 14 of the extension pieces until the lower end of 3| rests on the stop 26. The ends 3|, being of the same cross-section as the slots I4, will fit snugly therein. Key pin 28 which is of wedge construction is then vertically forced into the cooperating keyways on the extension and the outer end of the frame. Forcing the key pin into the key slots will force the ends of the frame against the walls of the slot thereby holding it in rigid position. Clamp bands 23 and 24 are bolted to the cornerpiece when the sign is securedto post I so as to form a permanent juncture. The sign holding frame and post engaging cornerpiece are manufactured of malleable iron.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent, is:

1. A sign holding device'lcomprising a body portion having a horizontally extending'holding arm, a. sign holding frame, said arm having a vertically arranged groove, said groove provided with a narrower width at its open side, and
